No Pain...No Money

The memorable opening scene of "Ghostbusters" features Bill Murray administering electric shocks to a college student for his incorrect answers during a test of the student's psychic ability.

In the real world, people were asked if they'd ever administer an electric shock to another person for money. 64 percent said no.

But when the opportunity (and the cash) was actually offered...96 percent of participants brought the juice.

Human psychology is fascinating.
